eq^2: 7x=84 divide 84 by 7 which is 12.
therefore x is equal to 12. Then
1) take that 12 you got in equation 2 and substitute in equation 1 which is:
7x-12y=180
7(12)-12y=180
84 -12y=180
-12y=180-84
-12y=96 ............divide both sides with -12
-y=8 (×-1) both sides
y= -8
therefore 7(12)-12(-8)=180
Answer:
FV= 200*(1.07^n)
Step-by-step explanation:
Current population= 200 deer
Growth rate= 7% per year
<u>To calculate the future value of deer in any given years, we need to use the following formula:</u>
<u></u>
FV= PV*(1+g)^n
FV= future value
PV= present value
g= growth rate
n= number of years
FV= 200*(1.07^n)
<u>For example, the population in 5 years:</u>
FV= 200*(1.07^5)
FV= 281
The answer is 512 ! To find this answer you can try 4*2 8 times since 4 is multipled by 2 continuously as a pattern.
Remember.
positive number x positive number = positive number
positive number x negative number = negative number
negative number x positive number = negative number
negative number x negative number = positive number
So if both numbers have the same sign, either both positive or both negative, then the product will be positive.
Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7
